Thanks for your patience Matthias, as this is actually a schoolboy
question about Erlang and a case of me not RTFM of gen_server. The
manual actually says, the init method returns the internal state of
the server which is passed to the handle_* callbacks. So I just passed
the module that implements the business logic via the supervisor to
the init method and the whole thing is *much* simpler. I'll consult
erlang-questions next time.
